27. An individual has the following genotype. Gene loci (A) and (B) are 15 map units apart, which determines their probability of recombination. 1) Indicate all the possible gametes that this individual can produce (with crossing over), 2) Label the gametes that are recombinant and non- recombinant. 3) Calculate the recombination frequency of the recombinant and non-recombinant gametes. The genes are not COMPLETELY linked. 28. Now imagine the genes are completed linked in #27. 1) What are all possible gametes?

Which statement explains why the recombination frequency between two genes is always less than 50%? Recombination cannot be more than 50% because chromosomes are only 50 map units in length. The genotype of the F, gametes will always be 50% parental gametes and 50% recombinant gametes. Genes with a recombination frequency near 50% are unlinked and have an equal likelihood of being inherited together or separately. F1 gametes always have 50% of their alleles from each parental...
